Rob Murray 084abd93d3 Add ErrDumpInterrupted
Add a specific error to report that a netlink response had
NLM_F_DUMP_INTR set, indicating that the set of results may be
incomplete or inconsistent.

unix.EINTR was previously returned (with no results) when the
NLM_F_DUMP_INTR flag was set. Now, errors.Is(err, unix.EINTR) will
still work. But, this will be a breaking change for any code that's
checking for equality with unix.EINTR.

Return results with ErrDumpInterrupted. Results may be incomplete
or inconsistent, but give the caller the option of using them.

Look for NLM_F_DUMP_INTR in more places:
- linkSubscribeAt, neighSubscribeAt, routeSubscribeAt
  - can do an initial dump, which may report inconsistent results
  -> if there's an error callback, call it with ErrDumpInterrupted
- socketDiagXDPExecutor
  - makes an NLM_F_DUMP request, without using Execute()
  -> give it the same behaviour as functions that do use Execute()
